Hey whats up for some reason my boost controller is not working right and i need some advice. I had it running at 15psi for around 6 months and for some reason now it wont stop climbing to 20. I re did all the setting and still its like the settings dont help it just wants to climb right around 20 psi. Could this be something wrong with the solenoid or something. All hoses are fine no tears or anything. If anyone has some setting they could share with me for 10-15 psi range i could try it would be much appreciated. Any advice will help im just getting really frustrated.

 

did you by any chance change to a better intake or exhaust?

 

nope everything is the exact same only mods that have changed are suspension i did take my map sensor off so my friend could try it on his car but i put it right back on vacuum line is zip tied tight im also running a sakura motorsports standalone but i didnt figure the tuning could be the problem

 

My spec B has issues as well.. It won't hold more than 13pounds no matter what I got it set at. I was told I would have to send it in to get it fixed.. Either way annoying..

 

I would do a boost leak test with the key in the 'ON' position, but don't start the car. Set the boost controller to your desired boost level and evaluate the boost solenoid.

 

How would i go about doing that?

 

Also the blue led goes red right upon start up for a split second then goes back to blue and when im on the warning screen and the limiter screen it glows red. Anyone elses do that? Maybe its showing that the limiter is screwed up and wont stop it from climbing past my set boost? Im lost someone help me out haha

 

You can test the solenoid simply by tapping it with a 12 volt battery...if you hear it click then its doing it's job...If you don't have a boost leak tester you could 'T' into the vacuum line you have going to the back of the Greddy controller and then use an air compressor and regulate it to 15psi and see if it kicks the solenoid on, as well as see what the display unit is doing along with the warning features etc.

 

what part would i tap with the battery?

 

Where is the spring located for the wastegate? im not too familiar with turbo systems

 

geeze i feel like an idiot this was the problem all along goes to show make sure you check everything out it hade a vacuum nipple on it but the top of it was hanging on by a thread of rubber
